River board Savoie

Flotilla of 7 river board near Bourg-St-Maurice in the Isere rapids
You are master of your own hydrospeed board


Below you will find the prices for our two offers navigating the Isere in Savoie by hydrospeed. The route goes from Bourg-Saint-Maurice to Gothard or from Bourg-Saint-Maurice to Aime, depending on your age and level of skill.

Naturally, we also have full day or weekend formulas combining several whitewater activities. During your stay in Bourg-Saint-Maurice, Les Arcs, Tignes, Val-d'Isere and La Plagne, etc. you can try out rafting in the morning and then hydrospeed, or whitewater swimming, in the afternoon, or canoeing or canyoning. You get to create your own white water formula.


Whitewater swimming in the River Isere, commonly known as hydrospeed (here in the Isere but it could also be hydrospeed in the Ubaye) is the most popular white water activity, along with rafting from Bourg-St-Maurice to Centron.

For hydrospeed, the swimmer is equipped with a foam board, a full body neoprene wetsuit with protective pads, and flippers for propulsion. This equipment is, of course, supplied by River Runners.

Hydrospeed means swimming down a river using flippers and the current. Hydrospeed is a more physically demanding activity than rafting. With it, you can very easily enjoy the unique sensation of river surfing. A fantastic experience! You need to be in good physical condition and a good swimmer if you want to hydrospeed - you also need to know how to swim with flippers. You have to keep your wits about you and use the movement of the water, the obstacles and the waves to your advantage.

The trails are adapted to suit water levels and the experience of those taking part. We organise half-day hydrospeed outings which can be part of a weekend of activities, and we also run courses.

The Beginner hydrospeed trail

Whitewater swimming for beginner

This whitewater swimming trip takes place on the Haute-Isere: 90 minutes of adrenalin rush along 9 km of river. This course is classified Grade 3.

We will swim along the Beginner run from Bourg-St-Maurice to Gothard. This gives you the chance to gradually get the hang of the techniques and thrills of white water swimming. During the swim, everything is a chance to improve your skills on the river. You will learn to pick your line and carry out basic whitewater manoeuvres (eddy stops, getting out of an eddy, ferry).
